ALKALINE GAS ADSORBING ACTIVATED CARBON

摘要

PROBLEM TO BE SOLVED: To provide an adsorbent capable of excellently deodorizing even various alkaline gases at a high adsorption rate. SOLUTION: A phosphoric acid-carrying activated carbon formed by carbonizing and activating an org. compd. in the presence of a phosphorus component is used as the main component. The adsorptive activated carbon is produced by allowing an organophosphorus compd. reactive to the organophosphorus compd. to prepare a phosphorus component-contg. activated carbon precursor, then calcining and activating the precursor.
